Jets on Mars
Nature, August 2006. CO2 Jets on Mars: Scientists have now found a better explanation for the dark spots and fans found on the south polar region of Mars. These spots, which can cover tens of square kilometers, are visible in the cryptic region. Originally, it was suggested that the spots were soil, exposed after early defrosting...
All About Ice
Why Study Ice on Mars?
On Earth, there’s a plethora of variables driving environmental change, from natural processes to the activities of humans. While Mars is most similar to Earth of all the known extraterrestrial worlds, its climate is still extremely different from our watery abode. The recent discovery of ice on the red planet’s surface has given us a new climate driver to study....

Meteor Crater is a 180 m deep, 1.2 km diameter bowl-shaped impact crater in Northern Arizona, and has long been a terrestrial analog site for planetary exploration. During the 1960’s, Eugene Shoemaker trained NASA astronauts at the crater to prepare for the Apollo missions to the Moon. The Meteor Crater Sample Collection consists of geologic samples from the Meteor Crater ejecta blanket.
The goals for this website are to catalog completed geologic maps and to help track the progress of currently funded maps. If you would like to propose for a mapping investigation, check the appropriate planetary body in the map index or refer to the various mapping pages (linked under Maps above) to see which geologic maps may have already been published or are currently in progress.
